  • Filtering is based on "Anding" i.e if any one assigned filter returns false then form does not appear on the patient dashboard.
  • Current Role Filter uses role inheritance behavior in filtering a form. We can switch between use/do not use role inheritance by setting "Use Role Inheritance Comparison" Global Property value to yes/no.
  • All filters should have a single string parameter constructor which takes filter properties as input. This constructor can be used to initialize filter properties.
